Simulation And Experimentation Of Wave Energy Converter Of Inverse Pendulum

Energy and environment have always been the two main issues of the world today, as the abundant renewable green energy, wave energy has become a hotspot in the area of renewable energy. So far, more than 340 Wave Energy Converter (WEC) programs have been proposed around the world. As one kind of Wave Energy Converters, the Pendulum Wave Energy Converter has its commercial value.This paper is mostly about experimentation of wave energy converter of inverse pendulum. The main research is about three aspects, theoretical calculation, simulation and plant experiments. The theoretical calculation provides a theoretical basis for the design of the inverse pendulum and hydraulic system, while providing a reference for the working place of the device. The simulation studies research on the power stability of the device under wave force by AMEsim, and verify the feasibility of a digital combined cylinder. In the plant experiments, use the hydraulic cylinder to simulate wave force, study the power stability of device, and compare with the result of simulation.The main research content of this paper is as follow:In chapter 1, discusses the research background of the subject and research situation of the wave power converter, then presents meaning and content of the subject.In chapter 2, discusses the composition and the basic principles of the wave energy converter of inverse pendulum, presents the key technologies in the research. In chapter 3, based on Airy wave theory, calculates and analyses the wave force when the inverse pendulum fixed in the middle position. Then derive the capture energy efficiency of the inverse pendulum, and analyses the relationship of the depth of sea and the mechanical impedance of inverse pendulum.In chapter 4, based on the theoretical basis of the previous chapters, design the hydraulic system and select the components. Simulate the performance of the hydraulic system under simulated wave force by AMEsim. At the same time, for the special nature of wave energy converter, we propose a design of digital combined hydraulic cylinder, simulate when it works in the hydraulic system, and verify the feasibility.In chapter 5, plant experiments of the 5kW wave energy converter of inverse pendulum have been done to research the power stability of the device.In chapter 6, the main researches of the paper are summarized, and the outlook for future work is made.
